I'm trying to run an old DOS game on my computer. When I execute de file, a window says:
----------------------MAX-FX Error report-----------------
No EMS driver found!!
Please make sure that an EMS driver will be init in your
CONFIG.SYS File i.e.:

DEVICE=C:\DOS\EMM386.EXE RAM 2048


I use windows XP and the CONFIG.SYS file is empty

What should I do?
